I'll be looking forward to getting better carts soon to bring out the flavors a bit more. But... could I use 2 ohm, or lower, on an ego-t battery?
Absolutely,but just so you know they will drain your battery a bit more. However,I'll sacrifice a little battery life for performance ANY day

Boge 2.0 ohm are a great cart,however,the best carts I've found are the 1.7 ohm 1.8ml
smok Tech (aka Resurrectors) sold at Crystal Clear
vaping. They are like the Boge 2.0 ohms on steroids and,amazingly,are single-coil
